yeah....... but still as soon as you switch on...the bulb starts to glow....... this is B'cuz...
there're too many electrons present in a conductor rather than one electron.....
so...it doesn't matter that how slow an electron moves.... what matters is how many electrons travelled in that time....say in one second........ that depends on the density of electrons...
well.... I can't tell you what's the absolute velocity of electrons.....but yeah.... I know that it travels at about
0.00000004% of light...
hope it helps!!...
